Practice programming algorithms drawing stars

Draw a line

Create a function called createLine that creates a line of stars for the given length.

At star is * - "* " - an asteric followed by a space.

createLine(5); returns * * * * *

createLine(7); returns * * * * * * *

Returning an array

To make things testable all functions from here on should return an array filled with stars.

Use the print function to print the drawing on the screen.

The unit tests are giving you a good overview of the required results though.

Draw a square

Create a function called createSquare that can draw a square of stars for the given dimension.

Note:

• Use the createLine function
• The ``

createSquare(5); draws:

 * * * * * 
 * * * * *
 * * * * *
 * * * * *
 * * * * *

createSquare(7); draws:

* * * * * * *  
* * * * * * *  
* * * * * * *  
* * * * * * *  
* * * * * * *  
* * * * * * *  
* * * * * * * 

Draw a rectangle

Create a function called createRectangle that can draw a square of stars for the given width and height.

createRectangle(5,3); draws:

 * * * * * 
 * * * * *
 * * * * *

createRectangle(7,2); draws:

* * * * * * *  
* * * * * * *  

Draw a Triangle

Create a function called createTriangle that can draw a triangle of stars for the given base.

createTriangle(5); draws:

 *  
 * * 
 * * * 
 * * * * 
 * * * * * 

createTriangle(7,2); draws:

*   
* * 
* * *
* * * * 
* * * * * 
* * * * * * 
* * * * * * *

Draw a flat top Triangle

Create a function called flatTopTriangle that can draw a triangle of stars for the given base with a base on top.

flatTopTriangle(5); draws:

 * * * * *  
 * * * *
 * * *
 * *  
 * 

flatTopTriangle(7); draws:

* * * * * * *   
* * * * * * 
* * * * * 
* * * * 
* * * 
* * 
*

Draw empty square

Create a function called createSquareOutline that can draw a square of stars for the given dimension that is outline only.

createSquareOutline(5); draws:

 * * * * * 
 *       *
 *       *
 *       *
 * * * * *

createSquareOutline(7); draws:

* * * * * * *  
*           *  
*           *  
*           *  
*           *  
*           *  
* * * * * * * 

If your done

Try to create :

• a createRectangleOutline function,
• a createTriangleOutline function,
• a drawDiamond function.

Create the tests first.
